Abstract
The utility model discloses a main transmission chain system of a fully-integrated thin oil lubrication type wind generating set, which comprises a main bearing, a speed-up gear box and a generator; the thin oil lubrication station is placed in a cabin of the main drive chain system, and a distributor of the thin oil lubrication station respectively supplies thin oil lubrication to fixed points of the main bearing, gears of the speed-up gear box, bearings of the speed-up gear box and bearings of the generator quantitatively. The utility model discloses bearing etc. that can effectively guarantee in the main drive chain system need lubricated part operating temperature steady, and the extension needs lubricated part's operational life reduces the operational failure rate and improves system reliability.
Description
Technical Field
The utility model belongs to the technical field of wind generating set final drive chain system's technique and specifically relates to indicate a lubricated formula wind generating set final drive chain system of full integrated thin oil.
Background
At present, in the wind power generation industry at home and abroad, the wind power generation system comprises a direct-drive wind power generation unit, a double-feed wind power generation unit and a traditional semi-direct-drive wind power generation unit, main components of the wind power generation system, a speed-up gear box, a generator and the like generally adopt independent lubricating systems or lubricating modes respectively, the main bearings and the generator of most of the wind power generation units adopt a grease lubricating mode, the speed-up gear box adopts a thin oil lubricating mode, but the components adopting the grease lubricating mode are often worn and over-heated to cause premature damage due to insufficient lubrication, poor cleanliness and the like; or the speed-up gear box and the generator are partially integrated and adopt a thin oil lubrication mode, the speed-up gear box and the main bearing are partially integrated and adopt a thin oil lubrication mode, the main parts of the whole main transmission chain system cannot be lubricated by thin oil in the above modes, and the main transmission chain system adopting the partially integrated thin oil lubrication mode only can realize partial thin oil lubrication function because the lubricating oil tank is integrated in the gear box body or the main bearing seat, and the lubricating system is inconvenient to maintain and is easy to cause adverse consequences such as oil leakage, poor cleanliness, poor reliability and the like.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a lubricated formula wind generating set final drive chain system of full integrated thin oil, can effectively guarantee that need lubricated parts operating temperature steady such as bearing, the extension needs lubricated parts's operational life, reduces the operational failure rate and improves system reliability.
In order to achieve the above object, the present invention provides a technical solution: a main transmission chain system of a fully-integrated thin oil lubrication type wind generating set comprises a main bearing, a speed-up gear box and a generator; the thin oil lubrication station is placed in a cabin of the main drive chain system, and a distributor of the thin oil lubrication station respectively supplies thin oil lubrication to fixed points of the main bearing, gears of the speed-up gear box, bearings of the speed-up gear box and bearings of the generator quantitatively.
Furthermore, an oil tank, a main lubricating pump and a main pump filter element which are shared by the main bearing, the gear of the speed-up gear box, the bearing of the speed-up gear box and the bearing of the generator are arranged in the thin oil lubricating station.
Compared with the prior art, the utility model, have following advantage and beneficial effect:
the utility model discloses an it provides the thin oil force-feed lubrication to the integrated base bearing together to establish a shared thin oil lubrication station, the lubricated part of needs in step-up gear box and the generator, the cleanliness of lubricating oil is high, it is good to lubricate and the cooling effect, it is steady effectively to have guaranteed that the lubricated part operating temperature of needs such as bearing is steady, the extension needs the running life of lubricated part, reduce the operation fault rate and improve the reliability of system, and adopt the thin oil lubrication station of one set of sharing, the commonality is good, and is low in cost, the later maintenance and the change of being convenient for.
